How Often Do Solar (or Lunar) Eclipses Occur?
- One calendar year has a minimum of four eclipses, two solar and two lunar
- The last time there were seven eclipses in a single year was 1982, and the next time will be 2038
- Few people see the shallow solar eclipses that occur regularly in the Arctic and Antarctic regions
Is a solar eclipse more rare than a lunar eclipse?
Solar eclipses are not actually rarer than lunar eclipses – in fact, they occur in about equal numbers, usually about two of each per year. For example, between 2000BC to 3000AD there will be 11,898 solar eclipses and 12,064 lunar eclipses. However, at any one location on Earth, it is much less common to see a solar eclipse than a lunar one.
How to properly watch a solar eclipse?
- Record the time when the totality began and everything was plunged into darkness.
- Record the time when totality ended and everything became light again.
- You can figure out how long in minutes it took the moon’s shadow to pass over you by taking the difference between these times.
How often is it possible for solar eclipses to occur?
On average, it takes about 375 years for a total solar eclipse to happen again at the same location. By comparison, a total lunar eclipse, also known as a Blood Moon, can be seen from any location approximately every 2.5 years. On average, there are about 240 solar eclipses and a similar number of lunar eclipses each century.
What is more common a solar or lunar eclipse?
Thus, at any single location on Earth, a total solar eclipse occurs only once every 300 years or so. Because the shadow cast by the Earth is quite a bit larger than the Moon, lunar eclipses are more common than solar eclipses, and totality can last for about an hour.
How often is a solar eclipse visible?

Where Do Solar Eclipses Occur Most Often?
With the Moon crossing the orbital plane of the Earth, there are lunar nodes in the region. There is only one solar eclipse per year when the Earth, the Moon, and the Sun are aligned at that moment.
Why Do Solar Eclipses Happen So Often?
The number of solar eclipses might also increase on a weekly basis. Nevertheless, other factors contribute to keeping solar eclipses from occurring too often. As a result, the moon’s orbit resembles that of the equator of Earth. For the shadow of the sun to reach us, it needs to pass at just the right orbit of the moon for half a second.
How often does a solar eclipse occur?
It is a popular misconception that the phenomenon of a total eclipse of the sun is a rare occurrence. Quite the contrary. Approximately once every 18 months (on average) a total solar eclipse is visible from some place on the Earth’s surface. That's two totalities for every three years.
How to predict solar eclipse?
Predicting the details of a solar eclipse requires not only a fairly good idea of the motions of the sun and moon, but also an accurate distance to the moon and accurate geographical coordinates. Rough determinations of eclipse circumstances became possible after the work of Claudius Ptolemy (around A.D.150), and diagrams of the eclipsed sun have been found in medieval manuscripts and in the first books printed about astronomy.
What happens when the moon passes directly in front of the Sun?
This means that when the moon passes directly in front of the sun, it the lunar disk will appear slightly smaller than the disk of the sun , and skywatchers will witness what's known as an annular eclipse, with a dazzling ring of sunlight still visible around the moon's silhouette. Of course total solar eclipses do occur, ...

What is a total solar eclipse?
What Are Total Solar Eclipses? Total solar eclipses happen when the New Moon comes between the Sun and Earth and casts the darkest part of its shadow, the umbra, on Earth. A total eclipse is spectacular to see. During a total eclipse of the Sun, the Moon covers the entire disk of the Sun. In partial and annular solar eclipses, ...
Why are solar eclipses called total eclipses?
By convention, therefore, eclipses are named after their darkest phase—if a solar eclipse is total at any point on Earth, it is called a total solar eclipse. Hybrid solar eclipses or annular-total eclipses are an exception to this rule. This is because they change from an annular to a total eclipse or from a total to an annular eclipse along their ...
What happens during a total eclipse?

The midpoint of time of totality is known as the maximum point of the eclipse. Total eclipse ends (3rd contact): The Moon starts moving away, and the Sun reappears. Those fortunate enough to be in the Moon's umbral can see Baily's beads and the diamond ring effect just after totality ends. Partial eclipse ends (4th contact): The eclipse ends as ...
How many phases are there in a solar eclipse?
Complete Solar Eclipse Has Five Phases. There are five stages in a total solar eclipse: Partial eclipse begins (1st contact): The Moon becomes visible over the Sun's disk. It looks like the Moon has taken a bite out of the Sun. Total eclipse begins (2nd contact): The Moon covers the entire disk of the Sun.
What happens during a total solar eclipse?
A total solar eclipse — like the one that crossed the U.S. on Aug. 21, 2017 — occurs when the moon blocks 100% of the solar disk. If an observer is standing within the path of totality, they will notice a 360-degree sunset and see just the outermost layer of the sun, called the corona, during the total eclipse's peak.
What time does the solar eclipse start?
The partial solar eclipse begins at 2 a.m. EST (0700 GMT), the greatest point of the total solar eclipse occurs at 2:33 a.m. EST (0733 GMT) and the partial eclipse ends at 3:06 a.m. (0806 GMT), according to NASA . Below is a chart with some eclipse viewing times, featuring data from Time and Date.
What is the name of the event when the moon covers only the middle part of the Sun?
An annular eclipse occurs when the moon covers only the middle part of the sun, giving the event a "ring of fire" appearance. The amount of sun that the moon can block on a given eclipse encounter depends on where the moon is located in its elliptical orbit around the Earth.
What happens when the moon is in front of the Sun?
A solar eclipse occurs when the new moon, which is otherwise invisible, makes a rare appearance by crossing in front of the sun's face, slowly creating the appearance of a "bite" taken from the sun. This continues until the moon fully or partially blocks the sun's disk.
What do you need to watch an eclipse?
To safely observe the sun or watch an eclipse, you need special protective eyewear or eclipse glasses. Basic sunglasses, even those with UV protection, will not sufficiently protect your eyes. If you're planning to document the eclipse with any photo equipment, there are special solar filters you can add to make sure the remaining ring of sunlight doesn't take a toll on your vision.
When does the moon appear smaller than the Sun?
If the moon passes directly in front of the sun when it is near apogee, the point in its orbit where it is farthest from Earth, it will appear smaller than the sun in the sky. The moon partially covers the sun during an annular solar eclipse as seen in the Yemeni capital Sanaa, early on June 21, 2020.
When will the next solar eclipse be in 2021?
There are two solar eclipses in 2021. First, an annular eclipse commonly referred to as a "ring of fire," will occur on June 10 and be visible from parts of Canada, Greenland, the Arctic and Russia. Then on Dec. 4, a total solar eclipse will appear over the opposite pole, across the skies of Antarctica. December's eclipse will be the first and only ...
How often do solar eclipses happen?
Solar eclipses happen once every year-and-a-half or so; the trick is you're not always able to see them based on your vantage point on Earth.
What happens when you see a total solar eclipse?
During a total solar eclipse, you can see the sun's outer atmosphere, called the corona. In fact, this is the only time that you can see the corona, which is why astronomers get so excited when a total eclipse is about to occur.
What Is a Solar Eclipse?
Positions of the sun, moon and Earth during a solar eclipse. Umbra and penumbra are regions of the moon's shadow.
What is the name of the solar eclipse that only shows a small ring of light from the Sun's disc?
In some cases, the moon is far enough away in its orbit that the umbra never reaches the Earth at all. In this case, there is no region of totality, and what you see is an annular solar eclipse. In an annular eclipse, only a small, ring-like sliver of light is seen from the sun's disc ("annular" means "of a ring").
Why is it called an eclipse season?
These times are called eclipse seasons, because they are the only times when eclipses can occur. For an eclipse to take place, the moon must be in the correct phase during an eclipse ...
What are the two parts of the moon's shadow?
The moon's shadow has two parts: a central region ( umbra) and an outer region ( penumbra ). Depending upon which part of the shadow passes over you, you will see one of three types of solar eclipses:
How to observe the sun?
The best way to observe the sun is by projecting the image. Here is one way to project the sun's image: Get two pieces of cardboard ( flaps from a box, backs of paper tablets). With a pin or pencil point, poke a small hole in the center of one piece (no bigger than the pin or pencil point). Take both pieces in your hand.
How much do eclipse glasses cost?
Many companies sell inexpensive “eclipse glasses” made of cardboard, with plastic Mylar filters. They work. The cardboard types run about $10 for a 4-pack. The American Astronomical Society has compiled a list of vendors where you can buy safe eclipse glasses.
Can you see the Sun through a camera?
Do not look at the Sun through a camera without a special solar filter—nor while using your eclipse glasses or solar viewer. The concentrated solar rays will damage the filter and enter your eye (s), causing serious injury. Even if you buy a special solar filter for your camera, shooting an eclipse is challenging, requiring the photographer to shift from too much light to shooting in the dark when you need a fast lens. If you’re a beginning photography, we’d put the camera down during the 2-minute event, soak in the experience, and look at the thousands of photos taken by professionals after the event.
Is It Safe to Look at a Total Solar Eclipse?
The Sun has been moving behind the Moon for the past 50 minutes. Soon, the Sun will appear as a thin sliver, like a slender crescent Moon. In a minute, even this gets reduced in size. You look at the ground around you; it’s getting darker. If you are within the path of totality, you want to see the famous “diamond ring” that happens just before totality begins. Is it okay to then take a quick squinting glimpse at the Sun?
Is It Safe to Look at the Sun?
I’m in touch with a man who suffers permanent eye damage from looking straight at the Sun decades ago. True, he used binoculars, which can cause permanent blindness in just a second or two. But it brings up that ancient eclipse question: what is the actual, unexaggerated danger of simply peering at the Sun directly?
